Microchip Technology MIC826WYMT-TR Voltage Supervisor
The MIC826WYMT-TR from Microchip Technology is a highly precise, compact voltage supervisor designed to monitor power supplies in digital systems. Its primary function is to assert a reset signal whenever the monitored power supply voltage drops below a predetermined threshold, ensuring reliable operation of microcontrollers and other digital devices by preventing them from operating under conditions that could lead to unpredictable behavior.
This particular model comes in a small 6-TDFN (2x2mm) package, which makes it ideal for space-constrained applications. Despite its diminutive size, the MIC826WYMT-TR packs a powerful punch in terms of performance and features. It offers a low quiescent current, typically around 1.6µA, making it suitable for use in battery-powered devices where power conservation is crucial.
Key features of the MIC826WYMT-TR include:
- Adjustable Threshold Voltage: The device allows users to set the voltage threshold according to their specific requirements, providing flexibility across different applications.
- Manual Reset Input: An additional manual reset input is provided, enabling users to trigger a reset manually when necessary.
- Watchdog Timer: An integrated watchdog timer helps to ensure that systems continue to operate as expected by monitoring the activity of the microcontroller and initiating a reset if it becomes unresponsive.
- Power Supply Glitch Immunity: The MIC826WYMT-TR is designed to ignore fast transients on the power supply line, which helps prevent false triggering of the reset signal.
- High Accuracy: With tight threshold accuracy, the device ensures reliable monitoring and control of power supply levels.
The MIC826WYMT-TR is also characterized by its wide operating temperature range, from -40°C to +125°C, which allows it to perform reliably in extreme environmental conditions. This makes it an excellent choice for industrial, automotive, and other high-reliability applications.
Overall, the MIC826WYMT-TR is a robust, versatile voltage supervisor that offers designers a high degree of protection for their digital systems, ensuring that devices operate within safe voltage parameters and maintain system stability.
